The CNC machine tool CNC machine tool paper Fault diagnosis and maintenance of the electrical control system of CNC machine tool Abstract: the electrical control system of CNC machine tools is the main part of the machine tool mechanical and electrical integration of CNC, this paper mainly expounds the diagnosis of CNC machine electrical control system fault detection, preventive maintenance of electrical system troubleshooting method and CNC machine electrical control system. Abstract: CNC machine electrical control system is a major component of mechanical and electrical integration, this paper describes the control system fault diagnosis of CNC machine electrical control, electrical system troubleshooting method and numerical control machine tool preventative maintenance of electrical control system and other issues. Keywords: CNC machine tools; electrical control system; Key words: CNC machine tools site maintenance Electrical; control system; field maintenance classification number: TG659 document code: A article number: 1006-4311 (2011) 03-0263-02 0 Introduction CNC machine tool is a machine, electricity, liquid and gas in one of the electromechanical integration equipment, electrical control system of CNC machine tools is the core of its reliable operation, directly related to the The equipment operation is normal or not. When the electrical control system fault, fault diagnosis should be quickly, eliminate accidents, restore normal, and should carry out preventive maintenance, which is very important for improving the efficiency of NC equipment. 1 electrical control system fault diagnosis and detection 1.1 it is the use of intuitive judgment of our senses that may occur the phenomenon of fault and diagnosis.
